Graf gravity meter and part

Gravimeters are scientific instruments which use an extremely sensitive weighing device to measure the strength of gravitational waves. Changes in gravity are measured by weighing and re-weighing the same object in repetition, observing minute changes in the object’s weight when under slightly more or less gravity.

A common use of sea gravimeters was to prospect for undersea oil fields on submarines, which started to become more common from the 1930s onwards, in particular in the immediate post-war period.

This example is a model of sea gravimeter, possibly a prototype, designed by Professor Anton Graf who, under the employ of Askania Werke in Berlin, developed the first sea gravimeters in 1938. Anton Graf would later introduce an improved model of sea gravimeter in 1957.
